| Abstract: | Many people have difficulty sleeping. A 1995 survey by Gallop found that 49% of adults were dissatisfied with their sleep at least 5 times per month. It has been estimated that 10% to 40% of adults in America have intermittent insomnia; while 10% to 15% have long term sleep difficulties. The American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) defines insomnia as a complaint regarding the quantity, quality, or sleep timing at least 3 times a week for at least 1 month. Research studies define insomnia as a sleep latency (time taken to fall asleep) that is greater than 30 minutes, sleep efficiency (time asleep/time in bed) less than 85%, or sleep disturbance more than 3 times a week. Insomnia has been associated with decreased work performance as well as increased motor vehicle accidents. Cost estimates for lost productivity and insomnia related accidents exceed $100 billion per year. Numerous controlled clinical trials have demonstrated that improving insomnia with pharmacological treatment reduces sleep disturbance. However, the side effects, poor compliance rate, and cost of these drugs have stimulated the search for other options. Recently, behavioral techniques such as yoga, relaxation, and meditation also have been shown some success in treating insomnia. All these behavioral techniques have as an active component, lowering physiological arousal. Thus, accumulating evidence suggests that techniques assisting with decreasing physiological arousal have a beneficial effect on sleep disturbance. For this reason, an empirical investigation of the role yoga may have in the treatment of sleep disturbance appears warranted. The purpose of this study was to assess the effectiveness of a Kundalini yoga intervention on sleep disturbance. Participants with sleeping difficulty were recruited from the San Diego community. Thirty-two participants were alternately assigned to either a weekly yoga group or a music control group. The yoga group practiced Kundalini poses specifically shown to benefit sleep, over an 8-week period. Outcome measures included Pittsburgh Sleep Diary, Arousal Scale, Profile of Mood States and the Epworth Sleepiness Scale. Data were analyzed for 32 participants (15 treatment, 17 control) ages 22-35 who had a sleep disturbance (PSQI>/=5). Yoga participants reported significant improvement in wake-time after sleep onset (p = .03) and quality of life (p = .04), compared to music controls. Yoga led to significant improvements on QOL and one sleep parameter (WASO). The majority of sleep variables improved across time in both groups, however differential effects of yoga were not found. Both yoga and music may be potentially promising treatments for managing sleep difficulty, however future research with an additional no treatment control is needed.
